 ALGORITHM is a symbol specifying the hash to use:
-md5, sha1, sha224, sha256, sha384 or sha512.
+- md5    corresponds to MD5
+- sha1   corresponds to SHA-1
+- sha224 corresponds to SHA-2 (SHA-224)
+- sha256 corresponds to SHA-2 (SHA-256)
+- sha384 corresponds to SHA-2 (SHA-384)
+- sha512 corresponds to SHA-2 (SHA-512)
 
 The two optional arguments START and END are positions specifying for
 which part of OBJECT to compute the hash.  If nil or omitted, uses the
